In my research on trailering and tow vehicles, I came across a new standard for establishing towing capacity ratings for light trucks/SUV's, etc.

SAE J2807 came into effect on/about 2015 model years.

Toyota tried that back in 2013 IF I recall correctly. That's when their 5.7L Tundras dropped from 10k towing to around 7k towing. I know, I owned one and questioned it at the time as to what the major change was. This was the answer - new standard.

Toyota went away from that as my 2016 Tundra was back up to the 10k towing.

Then there’s the differences in tow ratings of similar vehicles sold in the US, Europe and Australia. They seem to be rated the lowest here. For example Jeep Wranglers are rated here at 3500 lbs but 5500 lbs in Australia. I don’t see how my old 98 4.0 Grand Cherokee was rated at 5,000 lbs yet a modern Wrangler that is the same size, weighs a lot more, has 80 more horsepower and much better brakes is rated at only 3500. Even the wheelbases are about the same.

It's actually a decent standard all things considered. We had 2 company trucks from GM, one before and one after they made the switch. IIRC it dropped about 300lbs by adhering to the standard. They were same chassis/generation and engine configurations other than one being rated for j2807 and one not.
